The structure of the eyes is explained by means of models and diagrams. The film also shows why and how common defects, diseases and injuries should be treated: long- and short- sightedness, astigmatism and squint; blepharitis, conjunctivitis and styes; grit and dirt. It is important that the eyes are not strained in reading or by close needlework, and above all that the children are kept happy and in good general health.
